    Abstract: The compsns. (I) comprise, on wt. (A)-(E), (A) 3-97wt.% resin contg., on wt. (A), (a1) 60-85wt.% at least one 8-9C vinylaromatic monomer and (a2) 40-15wt.% acrylonitrile units; opt. (B) up to 40wt.% elastomer of glass temp. below 0 deg.C as graft copolymer from (a1) and (a2); (C) 97-3wt.% poly(phenylene ether); (D) 0.5-40wt.% at least one P-contg. flame retardant cpd.; and (E) 0.3-95wt.% at least one copolymer comprising terpolymeric main chain with side chains attached through condensn. Wt.-average mol. wt. (by G.P.C.) of main chain of component (E) is 10 power 4 to 10 power 7, and that of side chains is 200-22000. The main chain contains, polymerised, (e1) 60-91wt.% at least one 8-9C vinylaromatic monomer, (e2) 40-9wt.% acrylonitrile, and (e3) 0.3-10wt.% at least one ester of (meth)acrylic acid with an ester-forming alcohol. Each side chain has at least one, opt. unsubstd., poly(phenylene ether) residue (PPE) which links, via the gp.X (residue of an at least bifunctional couplinq agent), the polymer -XPPE of the side gps. to the monomer(s) capable of ether formation (i.e., side chains -XPPE are linked to O atoms directly attached to main chain).

    Abstract: The invention relates to a thermoplastic moulding composition containing A from 20 to 80% by weight of a thermoplastic polysulphone resin (polyarylene-polyether-polysulphone), B from 10 to 60% by weight of a polycarbonate, C from 5 to 50% by weight of at least one copolymer based on c1) at least one vinylaromatic monomer from the group consisting of styrene, alpha -methylstyrene and p-methylstyrene, or mixtures thereof, and c2) acrylonitrile, and D from 5 to 50% by weight of at least one graft copolymer comprising, in each case based on C, d1) from 50 to 90% by weight of at least one elastomer (rubber) and d2) from 10 to 50% by weight of at least one shell grafted onto the elastomer, is characterised in that the copolymer C used contains, based on C, from 88 to 73% by weight of the vinylaromatic monomer c1) and from 12 to 27% by weight of acrylonitrile c2) in copolymerised form, and the viscosity indices are in the range from 50 to 100, and that furthermore, a graft copolymer D having a mean particle size in the range from 80 to 500 nm is used whose elastomer d1) contains, in copolymerised form, d11 at least 80% by weight of butadiene and d12 from 0 to 20% by weight of styrene and/or acrylonitrile, and whose shell c2 contains, based thereon, d21 from 90 to 10% by weight of styrene and d22 from 10 to 90% by weight of methyl methacrylate. The moulding composition is used for the production of mouldings.
